DEVICE FOR SHIFTING THRESHlNG-MACHINE BODIES.

SPECIFICATION forming part of Letters Patent No. 744,334, dated November 17, 1903.

Application filed August 14, 1903. Serial No. 169,525. (No model.)

To aZZ whom it may concern:

Be it known that I, GEORGE GRAHAM, a citizen of Canada, residing at Rounthwaite, in the Province of Manitoba and Dominion of Canada, have invented new and useful Improvements in Devices for Shifting Thresh ing-Machine Bodies, of which the following is a specification.

' My invention pertains to devices for shift in g the body of a threshing-machine laterally on its axles with a view of placing said body in alinement with an engine for driving the machine and assuring the connecting-belt remaining on the belt-wheels of the machine and engine; and it consists in the novel and advantageous construction hereinafter declaims appended.

In the accompanying drawings, forming part of this specification, Figure 1 is a front elevation of a threshing-machine frame with parts in section and my improvements applied. Fig. 2 is a plan view. Fig. 3 is a detail sectional view taken in the plane indi cated by the dotted line 3 3 on Fig. 1. Fig. 4 is a front elevation illustrative of a modification hereinafter referred to, and Fig. 5 is a transverse section taken in the plane indicated by the line 5 5 of Fig. 4.

My invention contemplates providing shifting devices in connection with the front and back axles of a threshing-machine; but as the said devices are similar in construction I have deemed it sufficient to illustrate one device in connection with the front axle of the ma chine.

similar letters designate corresponding parts in all of the views of the drawings, referring to which- A is the body of a threshing-machine having longitudinal bars a at its under side.

B is the front axle, and O is a bolster interposed between the body and the axle and suitably connected to the latter.

D D are parallel transverse bars disposed below and fixedly connected to-the bars a of the body; E E, antifriction-rollers journaled in the bars D and bearing on the upper side of the bolster C; F F, U-shaped metallic straps receiving and fixedly connected to the bolster, and G G antifriction -rollers jour naled in the end portions of the straps F'and I rection of its width on the axle.

bearing on the upper sides of the barsD. In virtue of this construction it will be observed that the bars D are adapted to move endwise on the rollers E,which bear on thebolster O and under the rollers G, and in consequence the body A may be very easily moved in the di- It will also be observed that the lateral movement of the body will be attended with but little friction and but little-or no wear of the parts.

H is a lug fixedly connect-ed to and depending from the middle of the front bar D and having a transversely-disposed threaded aperture b. w

I I are bearings arranged on theforward side of the bolster C. 1

J is a shaft journaled in the bearings I and having a threaded portion 0, disposed in the threaded aperture 1) of lug H, and also having an angular end d, and K is a removable crank having an angular socket e to re- 2 ceive and engage the said angular end of the shaft.

The crank is designed to be passed between the spokes of one of the wheels on axle B and placed in engagement with the angular end of the shaft J after the manner shown.

WVhen the crank K is applied, as above stated, and rotated it will be observed that theshaft J will also be rotated and the body A moved sidewise to the left or right, according to the direction of rotation of the crank and shaft. It will also be observed that because of the antifriction devices before described and the leverage afforded the body may be quickly shifted to the extent desired 'with but a minimum amount of effort on the part of the operator.

As will be gathered from the foregoing the bars D constitute a carriage connected to and movable with the body A and connected with the axle B and movable'with-respect to the same in the direction of the length thereof, also that the said carriage carries traveling rollers to ease its movement. 7

In the modification shown in Figs. 4 and 5 the carriage D is formed of a casting instead of bars, as in Figs. 1 to 3, and is arranged directly on the axle B and provided with antifriction-rollers E, which bear and are designed to travel on the axle.

is connected in a suitable manner to the body Said carriage A and is provided with a lug H, having a threaded aperture 1), receiving the threaded portion 0 of a shaft J, which is journaled in suitable bearings I on the axle. When the said shaft J is rotated through the medium of the crank K or other means, it will be observed that the body A will be shifted laterally on the axle.

As before stated, my invention contemplates the provision of a shifting device above the back axle of the threshing-machine as well as above the front axle, and I prefer to so arrange the devices that the forward end of the body may be shifted six inches either way and the rear end thereof four inches either way. This will permit of the body being properly alined with an engine under all conditions.

It will be appreciated from the foregoing that my improvements are simple and inexpensive and do not add materially to the cost of the machines in which they are embodied, also that the improvements may be readily applied to threshing machines of various kinds at present in use.

I have entered into a detailed description of the construction and relative arrangement of the parts embraced in the present and pre' ferred embodiments of my invention in order to impart a full, clear, and exact understanding of the same. I do not desire, however, to be understood as confining myself to such specific construction and relative arrangement of parts, as such changes or modifications may be made in practice as fairly fall within the scope of my invention as claimed.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s

1. In a device for shifting vehicle-bodies on their axles, the combination of an axle, a bolster thereon, a body connected with and movable in the direction of its width on the bolster, a lug connected with the body, and having a transversely-disposed, threaded aperture, and a transverse shaft journaled in bearings, on the bolster, and having a threaded portion disposed in the threaded aperture of the lug.

2. In a device for shifting vehicle-bodies on their axles, the combination of an axle, a bolster thereon, a body connected with and movable in the direction of its width on the bolster, antifriction-rollers interposed between the bodyand the bolster, a lug connected with the body, and having a transversely-disposed threaded aperture, and a transverse shaft journaled in bearings, on the bolster, and having athreaded portion disposed in the threaded aperture of the lug.

3. In a device for shifting vehicle-bodies on their axles, the combination of an axle, abolster thereon, a body, a transverse bar carried by the body, straps connecting said transverse bar and the bolster, antifriction-rollers carried by the straps, and bearing on the transverse bar, antifriction -rollers interposed between the transverse bar and the bolster, a lug connected to and depending from the transverse bar, and having a transverselydisposed, threaded aperture, and a transverse shaft j ournaled in bearings, on the bolster, and having a threaded portion disposed in the threaded aperture of the lug.

4.
